Strong coupling of a single quantum system to an optical resonator is a hallmark of quantum optics. It is characterized by the repeated coherent exchange of a single excitation between the emitter and the resonator. We study strong coupling of single emitters to plasmonic nanoresonantors at room temperature. We position emitters within the ultrasmall subwavelength mode volumes of broadband plasmonic nanoresonantors using high-end nanofabrication. The goal is to achieve deterministic photon-emitter interaction for quantum communication, quantum sensing, as well as the development of novel quantum optical imaging modalities.
